If you are accepting of slugged plastic chips, Chiplab.com has really good chips that you can customize with quick turnaround time. I designed chips from them for 2 of my friends and we play with those chips every week. Solid chips. The more you order, the lower the price per chip. However, you cannot customize the edge spots and they cost slightly more than Broken Arrow cardroom chips at the current time.
Warning: Only consider Chiplab "clay" chip line. The other chips are a waste of money.
Personally, I'd rather the new Broken Arrow hybrid chips IF you don't mind the wait.
